Application led June l, 1905. Serial No. 263,282.

To @ZZ whom t may concern:

Be it known that I, GREGORY GERDOM, a citizen of the United States, residing at Watervliet, Albany county, State of New York, have invented a new and useful Breech- Block-Operating Lever, of which the following is a specification.

My invention relates to improvements in breech mechanism for ordnance, its object being to provide an improved construction of breech-block-operating lever 3 and it consists in the features of construction hereinafter described and claimed.

In the drawings forming part of this specification, Figure l is a sectional elevation of my improved lever; Fig. 2, a cross-section of the same, showing the catch for locking the same to the breech-block carrier. Fig. 3 is a plan view, and Fig. 4 is a detail.

In the drawings the lever A is provided with a pivot-pin hole 2, by means of which it is mounted upon the breech-block carrier, and has a handle 3 within a channel in which works the trigger 4. yThis trigger is secured to a sleeve 5, which is mounted to rock upon a pin 6, arranged in the body of the lever, and carries a catch7 adapted to engage a shoulder 8 upon the carrier 9. The pin 6 is held in place in the lever by means of a spring 10., secured to the pin and having a teat l1, which engages with a circumferential groove 12. This serves to hold the pin in place for use, but will yield when a tool is inserted underneath the shoulder of the head 13 and allow the pin to be withdrawn from the lever. The lever is channeled, as shown, on its under side to receive the sleeve 5 and pin 6, the sleeve and trigger being first slipped into place and the in 6 then inserted to secure them, the pin itself being held by its spring-catch.

By providing a sleeve 5 of sufiicient length I am enabled to oset the hook 7 and to locate the shoulder 8 at any convenient point on the carrier and to thereby do away with the necessity of placing a lug on said carrier immediately opposite the trigger, which is often inconvenient in this art. This feature of osetting the hook 7 for the above purpose I regard as important in this art.

The manner in which the described features operate in the use of the crank is evident. hand, the trigger 4 is pressed inward by the palm of the hand, thereby rocking the sleeve When the handle is pulled by the- 5 and lifting the catch 7 releasing it from the shoulder 8 and allowing the handle to be operated in the usual way to withdraw the breech-block.

I claim- 1. A lever of the class described having a spring-controlled trigger and offset hook, a sleeve rigidly connecting said trigger and hook, and a removable pivot-pin for said sleeve extending axially in the body of said lever.

2. In combination with the lever having a channeled handle and arm, a sleeve removably iitted to the channel in the arm, and provided at one end with a spring-controlled trigger tting into the channel in the handle and at the other end with a hook oHset from the trigger, and a removable, axiallyarranged pivot for said sleeve.

3. In combination with a lever having a longitudinal channeled arm and a channeled handle, a rocking lever removably arranged in the channel in said arm and journaled therein upon an axially-arranged lpivot-pin, said rocking lever being provided with a trigger fitting into the channel in said handle and a rigidly-connected offset hook adapted to arrange a catch on the breech-block carrier intermediate of the handle and the pivot of said lever.

4. A breech-block-operating lever having a removably-pivoted pin axially arranged in the body thereof a sleeve intended to rock up on said pin, and having at one end a springcontrolled trigger arranged in and projecting from a channel in the lever-handle, and at the other end a hook offset from said trigger and adapted under the tension of the spring of said trigger to engage a catch adj acent to said crank and intermediate of its handle and pivot.

5. A lever of the class described having a hollow body and handle, arock-sleeve removably litted to the space in said lever, and provided with a laterally-extending spring-'controlled trigger tted to the space in said handle, and a hook oifset from said trigger and fitted to a lateral channel in said lever and adapted to engage a catch on the carrier intermediate of the pivot and handle of said lever.

6. A breech-block-operating lever having a lockinghook intermediate of its handle and pivot a spring-controlled trigger for trip- IOC Iof

ping said hook offset therefrom and arranged l In Witness whereof I have hereunto set my in the handle of said lever, a rocking member hand, at the city of New York, this 24th day rigidlT connecting said trigger and hook, and of May, 1905.

a removable pin serving as a journal-support GREGORY GERDOM. for said rocking member said lever being ohan- Witnesses 1 neled to permit the assembling of said parts T. D. MERWIN,
